' FLOOR CGNSTRUCTION.

Application mea epm 22, 192e. serial No. 103,800.

fire to the supportingbeams of `floors of this type having closely spaced light steel beams upon which a thin floor slab is directly car-r ried.

l0 Further aims and advantages of the vinvention appear in connection with the fol lowing description of the illustrative em-` bodiment thereof shown in the accompanying drawing, whichis an isometric view and cross-section of a floor, the cross-section being in part on a line parallel to the support ing beams and in `part on a line at right 'angles tothe supporting beams.

The floor shown in the drawings comprises a floor slab 11 having a layer 12 of plaster board, sheet rock, fiber board, or other heat and sound insulating material on its lower face. This insulating layer preferably eX- tends across the spaces between the beams 13 and over the topv flanges thereof, forming continuous layer of' insulation between the slab and the beams. Holes may be left for such ties and ducts as are necessary or desirable for connecting the various parts of the floorstructure and accommodating electric wiring, sprinkler heads, steam pipes and other fixtures or appurtenances that may be carried below the ceilin and cannot be housed in the beam enc osing insulation hereinafter` described. A top finish of wood flooring 14 `or other suitable material may be provided, as is customary.

The beams 13 may be supported at their ends in recesses in the walls of the building, 40

(not shown) and are protected from heat and'dampness by a covering or housing 15 of plaster board, gypsum slab, or other known insulating material in the form of' `sheets or slabs.` The sheets or slabs may be supported in any suitable manner, as by nailing blocks 16, cut to fit over the lower flanges of the beams 13, and similar blocks 17 fitting beneath the upper flanges, to which the sheets or slabs are nailed or otherwise secured. The blocks `17 may be secured to the ioor slab by means of metal strips 18 which straddle the top flanges of the beams and are bent over the outer edges of the or by suitable hangers from the floor girders` blocks and nailed thereto. Molding strips 19, 20, may be used to cover the joints be- Weenthe ceiling 12 and the side and bottom sheets or slabs 15 if desired. The molding strips 19, 20, are preferably made ot thin metal, or wood encased in thin metal, so that they may be easily penetrated by brads or nails. (lther means for seeming the beam housing sheets or slabs in position with their top edges in place against theceiling sheets may advantageously be used, as preferred.

lfdesired the spaces within the housing 15 may be filled with gypsum, plaster or other cementitious material to fembed the spacing blocks and such ducts andpipes as may pass through these spaces, holes being left through the floor slab vinsulationl 12 for. this purpose when the floor slab ris poured.

y 1n the claims the term'tsheet-likeinsulating material comprises plaster' sheets, fiber board, gypsum slab, or other insulating matei-iai for the floor slab and beam housing, which is adapted for use in sheets, boards,

r orifice.

slabs and similar self-sustaining convenient forms. y

The invention is not restricted to the `embodiment shown, but what is claimed is as follows: n

1. The substantially fire proof and sound proof `floor construction comprising light weight steel beams spread at substantially uniform distancesapart, floor supports of sheet-like insulating material extending in a substantially continuous layer over and be.- i

tween said beams, sheetflile insulating material encasing said beams and adjoining the underside of' said iioor supports, and a floor slab of cementitious material upon said floor supports to form a continuous floor.

2. Thesubstantially fire proof and` sound proof floor construction comprising light weight steel `supporting' beams, floor supports of sheet-like insulating material extending in a substantially continuous layer over and between saidbeams, sheetlike insulating material supported byand encaslng said beams and adjoining the under side fof said fioor supports, and a floorrslab of eementitious material upon said floor supports to form a continuous floor.

3. In a floor construction comprising a floor slab supported on spaced parallel beams, heat and sound insulating material of sheet-like form arranged between said slab and the tops of said beams, and similar material secured beneath said slab insulating material and disposed around said beams whereby they are enclosed and protected on all sides.

4c. In a floor construction comprising a floor slab support-ed on spaced parallel beams, spacing members carried by said beams, he'at and sound insulating material of Sheet-like form arranged between said slabk and the tops of said beams, and sheetlilie heat and sound insulating material secured to said spacing members and disposed around said beams whereby they are euclosed and protected on all sides.

5. A protective covering ot' heat and sound insulating material for floor support` ing I-beams comprising spzacing blocks fitted to reston the lower flanges of a beain, insu,- lating material in sheet or slab form secured to said blocks on the sides of and beneath said beams, similar insulating material covering the top of said beam, and means for holding said insulating material iu place to form a complete enclosure for said; beam.

.6. A composite floor comprising spaced beams 13, a door slab ll carried thereby comprising a layer of sheet-like insulating material l2, spacing yand sijipporting blocks 16 carried by said beams, and housings 15 oi insulating material carried by said blocks and surrounding said beams, substantially as described. l

7. rlhe floor construction comprising metal beams, heat and sound insulating nonoombustible ioor support sheets resting upon the upper langesof said beams, con- Crete floor panels comprising metal reeniorcement above and adhesively secured to said floor support sheets and neat and sound insulating lnon-combustible beam casing,r members secured around the depending beams, blocking strips between said' casing members and beam flanges and means f or'at tacl ing said casing members to, said blocking strips and to the adjacent eeilin'g sheets,"

8.k rlhe floor construction spaoed beams, igloor support sheets of' sound proof non-comlnistible i material bridging the spaces between said beams andv resting upon the upper flanges thereof, a cement' concrete 'licor slab secured to said sheets, and beam easing members of sound proof heat insulating material in Sheet'ibrin enclosing the depending portionsfol;I said beams'ia'nd secured to said sheets.

In testimony whereof, l have signed my name to this specilication. i' l 'rHoMAs J, Fos'rnn.
